Shamrock Rovers remain top, but St Pats failed to close the gap after their loss.
The League of Ireland Premier Division title race took another twist on Friday night as both of the top two were beaten.
Leaders Shamrock Rovers suffered a 1-0 defeat away to Dundalk, while St Patrick's Athletic missed the chance to close the gap as they were beaten 1-0 by Shelbourne.
Those results mean Rovers stay top on 34 points, with St Pat's three points behind on 31.
Bohemians remain firmly in the hunt after a 2-1 win over Drogheda United, lifting them to 28 points, just six off the lead.
Derry City were held to a 2-2 draw by Waterford.
Attention now turns to Monday night's meeting between Sligo Rovers and Galway United, both sides looking to create some space above Waterford at the bottom of the table.
